CALLIONEPION. 179 



the spermatheca is longer than in Rumina, Achatina, Neo- 

 beliscus or Opeas, being caught with the gut in the loop of 

 the aorta, and consequently the spermatheca lies near the 

 heart, as shown in the diagram, fig. 3. In the wide teeth of 

 the median row, this genus differs from the Achatinidcz, where 

 I formerly placed it. The radula differs in no important 

 respect from that of Megaspira.

Shell rimate, turrited, narrow, subregularly tapering; sur- 

 face glossy, covered with a greenish cuticle, somewhat irreg- 

 ularly plicatulate, decussated by numerous minute spiral striae 

 or very short cuticular processes, which are lost by wear from 

 the greater part of the shell, and then appear as lightly im- 

 pressed lines. Whorls 9%, moderately convex, separated by 

 impressed sutures, the apex very obtuse, with depressed tip; 

 surface of the earlier 2*4 whorls cut into an evenly granose 

 pattern by close, deep, obliquely descending grooves inter- 

 secting at right angles; last whorl rounded at base. Aper- 

 ture irregularly ovate, slightly oblique, its length contained 

 3y 2 times in that of the shell; peristome thin, subacute, the 

 outer margin slightly expanded, columellar margin reflexed, 

 dilated, impressed at its insertion, bearing a low, narrow sub- 

 median oblique fold, continued inward as a low, cord-like 

 spiral lamella within the last whorl. Internal pillar slender 

 and nearly straight. 



Length 24, diam. 7, length of aperture 6.6 mm. 



Length 23.5, diam. 7, length of aperture 7 mm.

The peculiar apical sculpture separates this from all South 

 American Stenogyroid species known to me. When this 

 sculpture is obscured by erosion, as occurs to a greater or less 

 extent in many adult shells, the slightly expanded lip and 

 median fold of the columella are still obvious recognition 

 marks. The type is No. 71,258, coll. Acad. Nat. Sci. Phila.
